Implantation and diagnostics of endometrial receptivity.

OBJECTIVE: Literature review of endometrial receptivity in embryo implantation and its diagnostic possibilities. DESIGN: Literature review. SETTING: Department of Obstetrics and Gynecology, University Hospital, Faculty of Medicine, Palacky University, Olomouc; Institute of Molecular and Translational Medicine, Faculty of Medicine and Dentistry, Palacky University, Olomouc. RESULTS: Endometrial tissue is very dynamic, undergoing cyclic proliferation, differentiation and cell transportation, especially of immune system cells under the influence of circulating estradiol and progesterone. Endometrial remodelling during embryo implantation is controlled by decidual cells senescence and effectivity of their immunologic destruction. Endometrial receptivity can be assessed by transcriptomic profiling of endometrial biopsy using ERA system or proteomic analysis of either endometrial secretome or cervical mucus by gel electrophoresis (DIGE) or mass spectrometry (MS). CONCLUSION: With respect to recent discoveries in endometrial physiology and molecular biology, clinical application of proteomic approaches in research of potential biomarkers of endometrial receptivity could be of interest.

[Various approaches of endometrial preparation for frozen-thawed embryo transfer]. / Moznosti prípravy endometria ke kryoembryotransferu.

OBJECTIVE: Various approaches of endometrial preparation for frozen-thawed embryo transfer. DESIGN: Retrospective analysis. SETTING: Department of Obstetric and Gyneacology, Faculty of Medicine, Palacky University, University Hospital Olomouc. METHODS: Effectivity of frozen-thawed embryo transfers was carried out between January and August 2017 in the IVF unit at the University Hospital Olomouc. Results were compared among groups A, B, C with various approaches of endometrial preparation. Group A - natural ovulating cycle, group B - artificial cycle with oral estrogen, vaginal gestagen and group C - artificial cycle with transdermal estrogen and vaginal gestagen. One blastocyst (two blastocyst in five cycles) was transferred on day 6 post ovulation (group A) or after 6 days of using gestagens (group B, C). RESULTS: The highest pregnancy rate was observed in group C (56%), similar pregnancy rate was found in group B (52%) and the lowest was seen in group A (22%). All pregnancies in group A continued over 12 weeks, in group B continued 57 percent and in group C continued 56 percent of pregnancies. CONCLUSION: Frozen-thawed embryotransfers in natural cycles are highly time-consuming. Our study has demonstrated the lowest effectivity of frozen-embryotransfer in natural cycles. Artificial cycles managed by oral or transdermal form of estrogen have shown better results.

[Recurrent implantation failure and thrombophilia]. / Opakované selhání implantace embrya a trombofilie.

OBJECTIVE: Bring a comprehensive overview of the available knowledge about the importance of thrombophilic mutations in patients with recurrent implantation failure and summary of therapeutic options. DESIGN: Overview study. SETTING: Department of Obstetric and Gynecology, University Hospital Olomouc. METHODS: Analysis of literary sources and databases Ovid, Medline. CONCLUSION: Failure of implantation in the context of assisted reproduction is associated with impaired endometrial receptivity. In women with normal anatomy may affect the implantation of embryos during stimulation hormonal changes, immunological factors or thrombophilic mutations. Recurrent implantation failure patients should be tested for the presence of thrombophilic mutations. Subsequently, these patients should be individually consulted and low molecular weight heparin should be used only in indicated cases. According to the available data treatment is recommended only in patients with known acquired or inherited thrombophilic disorder.

[Acute abdomen in elderly patients]. / Náhlé príhody brisní v seniorském veku.

BACKGROUND: Ageing of Czech population and the increase of numbers of elderly people gives new tasks to whole medicine and surgery too. METHOD AND RESULTS: Presented paper shows some aspects of occurrence, diagnostics and treatment of acute abdomen diseases--inflammatory and intestinal obstruction--in patients older than 60 years. It compares the occurrence and treatment results at an identical surgical department 30 and 60 years ago and nowadays. CONCLUSIONS: Number of the treated patients older than 60 years increased four times during the followed period. Opposite to that, death rate of operated patients declined from 37.2% to today's 16.4%--undoubtedly thanks to modern good-quality perioperational treatment.

[Malignant somatostatinoma (brief overview and a case review)]. / Maligní somatostatinom (strucný prehled a kazuistika).

INTRODUCTION: Somatostatinoma is a rare, slowly growing tumor with malignity potential, most commonly located in the pancreas or duodenum. By the time its diagnosis is established, it is usually large and liver metastases are present. Increased concentrations of somatostatin, produced by pancreatic D cells or by intestinal mucosa, inihibit secretion of a number of GIT hormones, endocrine and exocrine pancreatic secretion. The clinical findings include symptoms of diabetes, dyspepsia, diarrhoea, steatorhoea, abdominal pain, hypochlorhydria, anemia. Sometimes, the finding is accidental. A CASE REVIEW: The authors present a case of somatostatinoma, detected accidentaly in a 72-year-old male. The tumor originated from the pancreatic head, partially spreading invasively into surrounding organs (duodenum), invading blood vessels and metastazing into peripancreatic lymphonodes. The tumor was asymptomatic and was detected as an accidental finding on ultrasound and CT abdominal examinations for the patient's urological disorder (vesicolithiasis). Pylorus saving hemipancreatoduodenectomy was performed and, on microscopic and subsequent immunohistochemical examination of the resecate, a well- differentiated endocrine, somatostatin- producing pancreatic carcinoma was verified.

[Idiopatic bowel disease]. / Idiopatické strevní zánety--profil chirurgicky resených nemocných.

On the basis of retrospective five years analysis the authors process the problematic of idiopatic bowel disease--Morbus Crohn and ulcerative colitis. They pay main attention to surgical issue--types of operations, differences between acute and elective surgery, perioperative problems and results.

GIST of pancreas.

Authors present the case (from the year 2003) of a 38 years old patient, female with large tumor in the abdominal cavity. Preoperative differential diagnostic examination showed either tumor of pancreas or left liver lobe. The surgery confirmed large tumor body of the pancreas. Histological and immunohistochemical examination determined gastrointestinal stromal tumor (GIST) of the pancreas from autonomous nerves with malignant character. Tumor was radically removed. In the postoperative period regular follow up was done at the department of oncology, abdominal ultrasound every 3 months, CT scan every 6 month. 2.5 years after operation the patient has no problems, CT scan is without signs of recurrent diseases. The analysis of GIST was performed in agreement with contemporary knowledge. According to the references, our case report GIST of pancreas is the first of this kind (till 2003).

[Exenteration procedures in the pelvis]. / Exenteracní výkony v páinvi.

Exenteration pelvic procedures are surgical options for treatment of locally advanced pelvic tumors. Due to the procedure's success rates, it has become a standard therapeutic procedure, when indicated. From the medical point of view, the following factors characterize the level of seriousness of these procedures: the fact that the procedure is extensive, its complicated reconstruction phase and high postoperative morbidity rates. From the patient's point of view, it is characterized by a principal change in the quality of life. In this case review the authors present their experience with a multidisciplinary approach to these procedures.

[Reconstruction procedures following pelvic exenterations]. / Rekonstrukcní výkony po exenteraci pánve.

OBJECTIVE: Review of reconstruction procedures following pelvic exenterations. DESIGN: Review article. SETTING: Department of Obstetrics and Gynecology, Department of Urology, 1st Department of Surgery, Faculty Teaching Hospital and 1st Medical Faculty of the Charles University, Prague. METHODS: Review and critical assessment of published data. CONCLUSIONS: Reconstruction procedures are important part of pelvic exenterations. The procedures are crucial for following quality of life. Currently the most frequently used techniques for isolated pelvic floor support are omental flaps (carpets), for combined reconstruction of pelvic floor and vagina TRAM (transverse rectus abdominis musculocutaneus flap). Reconstructions prolong operation time; however they are accompanied with low morbidity and some techniques decrease total morbidity of exenterative procedure. Total and posterior exenterations require sigmoideostomy in vast majority of cases. Low rectal anastomosis might be used in cases of supralevator procedures. They cause high morbidity especially in patients following radiotherapy. In these patients temporary diverting colostomy is being recommended. A bowel segment is usually used for urinary diversion following total or anterior exenteration. Golden standard remain the incontinent ureteroenterostomies using ileum or colon transversum. Currently continent diversions are considered more often due to encouraging results and good quality of life. Heterotopic diversions, with continent conduit and cutaneous stoma, are frequently used. Risk of serious complications, especially fistulas and stoma stenosis, after all types of diversions is possible to reduce by using appropriate bowel segment not handicapped by previous radiotherapy.

[Prevention, diagnosis and treatment of iatrogennic lesions of biliary tract during laparoscopic cholecystectomy. Management of papila injury after invasive endoscopy. Part 1. Prevention and diagnosis of bile duct injuries]. / Prevence, diagnostika a chirurgická lécba poranení zlucovodu behem laparoskopické cholecystektomie. Lécení poranení papily v dusledku invazivní endoskopie. Cást 1.--Prevence a diagnostika poranení zlucovodu.

INTRODUCTION: Endoscopic invasive procedures in 70th and 80th years leaded to decrease reoperations on biliary tree. Iatrogenic injury of the biliary tract have increased in incidence in the first decade with the introduction of laparoscopic cholecystectomy. Athough a number of factors have been identified with a high risk of injury ( and number of technical steps have been emphasized to avoid these injury, the incidence of the bile duct injury has reached at least double the rate observed with open cholecystectomy. Cholecystectomy is most frequently performed abdominal operation and the most serious complication associated with this procedure is accidental injury to the common bile duct (0.3-0.4%). This preventable technical error has tradicionally been thought to occur in one or more of three situations: 1. When the operator attempts to clip or ligate a bleeding cystic artery and also clips the common hepatic duct (Fig. 3a). 2. When too much traction has been exerted on the gallbladder so that the common bile duct has tented up into an albow, which was either tied off with ligature or clipped (Fig. 3b). 3. When anatomic anomalies were not recognized and the wrong structure is divided, for example, when the cystic duct winds anterior to the common bile duct and enters on the left side, or when the cystic duct joins the right hepatic duct rather than the junction of the common hepatic and the common bile ducts (Fig. 1, 2, 3cd). In anatomical incertain cases is discussed about cholangiography and cholecystocholangiography during laparoscopy cholecystectomy. Most patients sustained a bile duct injury are recognized in the weeks folloving laparoscopic cholecystectomy. Careful preoperative preparation should include control of sepsis by draining any bile collections or fistulas and komplete cholangiography. Long-term results are best achieved in specialized hepatobiliary centres performing biliary reconstruction with a Roux-Y hepaticojejunostomy. Success rates over 90% have been reported from several centres to date with intermediate follow-up. Papila injury increased with introduction of a invasive endoscopy. Risk of deadly retroperitoneal inflamation is very high. Injury require same surgery procedure as duodenum injury. OWN EXPERIENCES: In an article a review of experiences of the 1st surgery department of General hospital in Prague since 1971 in 1 017 reoperations on biliary tree was carried out. There was in 311 patients 164 hepatohepatostomies and 147 hepaticojejunostomies used (Tab. 1). By laparoscopic injuries were high hilar injuries (Bismuth IV) in last decade and hepaticojejunostomy was done in all cases. Died 6%, long term results are acceptable by injured patients with hepaticohepaticostomies in 70%, by hepaticojejunostomies in 90%. Reoperated were 10% patients (Tab. 1). Remnant patients were dilated endoscopicaly. Postoperatively morbidity was high, above 26%. In years 1995-2003 were 8 patients with papila injury and inflamation in retroperitoneum operated as a injured duodenum (Tab. 2). CONCLUSIONS: Better experiences with treatment of injured biliary tree and papila are in centres interested in hepatobilliary surgery which knowledge anatomy of hilus of liver and can make wide hepaticojejunostomy. Transfer of drained injured patient to centre is possible.

[Results of the large intestine resection in elderly patients]. / Výsledky resekce tlustého streva u nemocných ve vysokém véku.

The colorectal carcinoma incidence increases with age. The radical resection procedure significantly extends the survival period, when compared with other therapeutic approaches. The tissue damage may exceed the organ reserve capacity in cases of the elderly patients and may result in higher postoperative morbidity and mortality rates. The aim of this study was to compare the results and the surgical risks of the large intestine carcinoma resection procedure in elderly patients, compared to younger patients with the same diagnosis. THE PATIENT GROUP AND METHODOLOGY: The retrospective study summons up the clinical results of 3778 patients from all over the Czech Republic, who underwent primeoperations for the following diagnoses: C18--a malignant neoplasm of the large intestine, and C19--a malignant neoplasm of the rectosigmoideal junction, in 2001. The results are compared with our own patient group in the same time-period. The results were assessed according to the following age-group criteria: 21-59 yrs., 60-69 yrs. and over 70 yrs. of age. We assessed the following factors: age, diagnosis, incidence of early postoperative complications and duration of patients hospitalization. RESULTS: The patients in the 21-59 year-group and in the group over 70 years of age, had significantly different rates of early postoperative complications (12.3% vs 17.6%, p < 0.001). The rate of complications was twice as high in urgent procedures compared to planned procedures in all age groups (p < 0.001). The average hospitalization lasted 14.8 +/- 10.9 days. We discovered statistically significant differences in the duration of hospitalization among all three age groups respectively (p < 0.01). CONCLUSION: Based on our results, we believe the age itself not be an indication-limiting factor for the radical resection procedure for the large intestine carcinoma. The elderly patients benefit from its oncological radicality with acceptable rates of the postoperative complications risks. We believe even extensive surgical procedures to be feasible in cases of appropriately indicated elderly patients, and their surgical risks to be acceptable considering the expected benefits for the respective patient.

[Preoperative biliary drainage in the pancreatic head carcinoma]. / Piedoperacní biliární drenáiz u karcinomu hlavy pankreatu.

UNLABELLED: Hemipancreatoduodenectomy has remained afflicted with high postoperative morbidity rates. Preoperative icterus is considered a significant risk factor. Therefore, a preoperative biliary drainage has been considered a standard preoperative procedure. This study aims to assess the preoperative drainage of the biliary tract significance with respect to the postoperative complications rates. SUBJECTS AND METHODOLOGY: This retrospective study includes 304 patients after completed hemipancreatoduodenectomies, who were operated in the 1st Surgical Clinic of the 1st Medical Faculty of the Charles University and the General Faculty Hospital in Prague between January 1990 and December 2002. In this trial group, 144 patients had underwent preoperative drainage of the biliary ducts and 160 patients underwent surgical procedures without the preoperative drainage. RESULTS: In the trial group, no significant difference in the gender rates, the history of the risk factors, the surgical procedure duration, the perioperative blood loss and the disease stage was detected. The patient trial group with the preoperative drainage of the biliary ducts completed was statistically significantly older (p = 0.05), had higher serum bilirubin levels recorded (118, respectively 81, p = 0.01), had more complications recorded postoperatively (42.4%, respectively 25%; p = 0.05), and more infectious complications (29%, respectively 13%; p = 0.05) when compared with the trial group without the preoperative drainage completed. Upon comparison of the both groups, we have not detected any statistically significant differences regarding the time interval between the diagnosis and the surgical procedure, the hospitalization duration or the mortality rates. CONCLUSION: The operated who had had the internal drainage of the biliary ducts conduted preoperatively, suffered from more complications in total as well as from more infectious complications, compared with the patients without the drainage. On the other hand, the patients who had had the preoperative drainage completed were older and had had higher preoperative bilirubin levels. With respect to the above results we strongly advise the patients with the pancreatic head carcinoma to early consult a hepatobiliary surgeon. As far as the examination algorithm is concerned, we strongly recommend using not only the spiral CT, but also non-invasive methods of examination (the MRI and the MRI cholangiography).

[Initial experience in exenteration interventions in the pelvis]. / První zkusenosti s exenteracními výkony v pánvi.

OBJECTIVE: Discussion of experiences with pelvic exenterations. DESIGN: Case-report. SETTING: Department of Obstetrics and Gynecology, Department of Urology, Department of Surgery, Department of Pathology, Department of Clinical Oncology, General Teaching Hospital and Ist Medical Faculty of the Charles University, Prague, Czech Republic. METHODS: Presentation of 4 cases of pelvic exenterations. Discussion with published data. RESULTS: Altogether four cases of pelvic exenterations are presented, one case of supralevator total exenteration for recurrent cervical cancer, one case of infralevator total exenteration for recurrent vaginal cancer, one case of supralevator anterior exenteration in the treatment of locally advanced cancer of urinary bladder, and one case of supralevator posterior exenteration for recurrent vaginal cancer.

Severe late complication of appendicitis. Case report.

BACKGROUND: Diffuse necrotizing soft-tissue infections are severe due to their rapid progression; there is a vital need for settling proper early diagnosis. The task of the clinician is mainly in distinguishing localized infection from the diffuse process. CASE PRESENTATION: In our case report we demonstrate a 32 yr old man with a curious development of severe necrotizing infection of submucosis with gas production as a conclusion of perforation of Schloffer's tumour, which developed after appendectomy carried 20 years ago. CONCLUSIONS: In case of diffuse necrotizing soft-tissue infections only immediate surgical revision can confirm initial stages of severe forms of infection.

[How surgery has changed and is still changing]. / Jak se zmenila a mení chirurgie.

Previous half of the century has influenced surgery not only by enormous progress of the knowledge in medicine, but namely in the last decade, by the introduction of mini-invasive operation techniques. Because of the highly effective conservation treatment, the spectrum of operations has been changed as well as the tactics and techniques of individual surgical procedures. Perspectives of surgery are in further specialization, introduction of one-day operations, and in the continuous development of mini-invasive operation techniques. The share of robots in the clinical praxis and in the training of surgeons is still difficult to forecast.

[The plug system and laparoscopic hernioplasty in recurrent inguinal hernia]. / Plug systém a laparoskopická hernioplastika u recidiv tríselné kýly.

A total of 1511 patients were operated on at the 1st Department of Surgery Charles University in Prague during 1996 through 2000. Of this number, 81.3% underwent surgery for primary and 18.7% for recurrent inguinal hernia. Among the patients with recurrences, 81% had the first, 15% patients the second, and 4% at least the third episode of recurrent hernia. A total of 604 patients were operated on during 1999-2000, when a plug system (Bard Mesh Perfix Plug) was introduced into surgery protocols. Of this number, 113 patients had a recurrent hernia with an identical ratio of recurrences. The following plastic surgery interventions were carried out during the latter period: McVay-Lotheissen (54.2%), TAPP (26.5%), PHS (13.2%), Plug (3.3%), and Lichtenstein (2.6%). The following interventions were used when operating recurrences: McVay-Lotheissen (20.3%), TAPP (31%), PHS (21.2%), Plug (16.8%), and Lichtenstein (9.7%). During the 1-24-month follow-up period, recurrences occurred 1x after the TAPP procedure, 1x after McVay-Lotheissen, and 1x after the Lichtenstein procedure (95% and 88% patients who underwent plug and Lichtenstein procedures, respectively, were included in the follow-up). Comparison of plug vs. TAPP in patients with recurrent hernia (Plug/TAPP): mean age of patients: 62/45 years, length of operation: 66/48 minutes, overall post-operative morbidity: 9.4%/3.6%, hospitalization: 4.3/1.8 days, return to the working process 28 days (range 9-38 days) vs. 7.2 days (range 2-15 days). Both procedures can be considered safe and reliable interventions for treatment of recurrent inguinal hernia. They meet the requirements for elastic strength (more the plug procedure), closure, and bridging of defects even in several layers. The plug system can be implanted under local anaesthesia, it is capable of bridging large defects in a firm and elastic manner, and appears to be a very suitable solution for large defects in patients with advanced biological age. In these indications, the plug system brings many benefits but also the risk of more open access and greater "quantity" of materials. TAPP appears to be more suitable in younger patients with recurrences and large defects. We evaluate favourably in particular, all aspects of the postoperative period. An experienced team of surgeons is needed to achieve good results in both procedures.

[Organ torsion and abdominal symptoms--diagnosis]. / Torze orgánu a brisní symptomatologie--diagnostika.

The authors reflect on the etiology of torsions of intraabdominal organs and the testes. They mention anamnestic data, which may lead to suspicion of possible organ torsion. They analyze the clinical picture of a patient who suffered such an attack. The authors submit a list of diagnostic possibilities using modern imaging methods: sonography, computed tomography, angiography, scintigraphy and magnetic resonance. They discuss laparoscopy as a diagnostic and therapeutic method.

[Organ torsion and abdominal symptoms--case reports]. / Torze orgánu a brisní symptomatologie--kazuistiky.

Torsions are rare acute abdominal conditions and are mistaken for other more frequent diseases. The present work draws attention to the most frequent diagnostic errors. The authors present three cases of torsions of intraabdominal organs and two cases of testicular torsion. All patients attended their doctor because of abdominal pain. In four of five cases the patients were first treated for an erroneous diagnosis of acute abdomen. In the first case the torsion of the omentum was mistaken for diverticulitis of the sigmoid, later for an intraperitoneal lipoma, in he second case for cholecystitis, in the third case a patient with torsion of a myoma was indicated for surgery on account of acute appendicitis. In the fourth case incomplete torsion of the testis was mistaken for irritation of the appendix. In the fifth case where abdominal symptomatology dominated the correct diagnosis of testicular torsion was made and atypically spontaneous detorsion of the testis occurred.

[Treatment of metastatic liver tumors]. / Moznosti ovlivnení metastatických nádoru jater.

We had operated 72 patients for hepatic metastatic malignancies from 1991 to 2000. In 66 cases were colorectal metastases. Extend of operations were from no anatomical resections, segmentectomies to hemihepatectomies. Operating lethality was 5.5% and long time survival only 10%. In the same period we took arterial port for 22 patients for regional chemotherapy. Response rate was 20% patients. The first experience with radiofrequency ablation (we had 12 ablation procedure) show, that minimal invasive treatment (RFA) is good procedure for high-risk patients. If the patient is able to hepatic resection it will be still standard for treatment.
